FISH-PLATE.

SPECIFICATION forming part of Letters Patent'No. 726,760, dated April28, -1 903-.

Application iiled December 9 1902. Iv Serial No. 134,540. y(No model.) Y

To all whom t may concern:

Be it known th at I, CLARK H. RIGGLE, a citizen of the United States,residing at PleasantV ish-plates for railroad-joints and means for vsssecuring them; and the object of the same is to construct a device whichwill not work v loose and will firmly secure the trackagainst spreading.

The simple and novel construction employed by me in carrying out myinvention is fully described and claimed in this specieation andillustrated in the accompanying drawings, fcrming a part thereof, inwhich- Figure 1 is a transverse section of a track equipped with mydevice. Fig. 2 is a plan view of the same. Fig. 3 is a detail ofthefish-plates. Fig. 4 is a detail of the clamp.

Like numerals of reference designate like parts in the dierent views ofthe drawings.

In the drawings are shown a raill, which forms-one side of a track, andtwo abutting rails 2, which form the other side of the track. The trackis supported on ties 3, and the rails 2 have apertures 4 in the endsthereof to acplate bearing studs designed to t apertures commodate studs5, formed on a fish-plate 6. The studs 5`pass through the apertures 4and engage a iish plate 7, having apertures 8 therein. A clamp 9 securesthe plates 6 and 7 together and comprises a stationary jaw 10 and asliding jaw 11, mountedin guides 12` and actuated byan adjustingorolamping screw 13',bearing on the rear end thereof. Y The guides 12vare formed von a headi14, which bears a threaded neck 15, which is'engaged by a turnbnckle 16, which also engagesfa threaded shank 17,bearing a claw 18,'whichY then engaged on the rail 1 and the turnbuckletightened. It is now evident that by my de Vice the ish-plates aresecurely held and the track held againstr spreading. v

I do not wish to be limited as to details of construction, as these maybe modified in many particulars without departing from the spiritof myinvention.

Having thus described` my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of the class described, the combination of ahead bearinga fixed jaw and a sliding jaw, means for clamping said jaws to secureiish-plates, a threaded shank bearing a claw, and a turnbuckleconnecting said head and said threaded shank, substantially asdescribed.

2. In a device of the class described, the

-combination of a head-bearinga fixed jaw and a sliding jaw coperatingwithsaid fixed jaw, means for securing said jaw against move designed toengage one railwhile said irstf mentioned jaw engages the other rail ofa track,and a turnbuckle engaging said Shanks,

substantially'as described. A

3. In a device of the class described, a fishin abutting rails, afish-plate having apertures fitting over said studs,'a head providedwith jaws-engaging and securing. said iishplates, and a claw bearing ashank adj ustably connected to said head, said claw being designed toengage the rail on the other side of lmy hand in presence of twosubscribingfwitnesses.
